Home > Article > PHP Framework > Laravel Passport builds API authentication and authorization
First step
Execute the following command:
composer require laravel/passport php artisan migrate php artisan passport:install
Second step
Modify Gurds in the config/auth.php file:
...
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'passport',
'provider' => 'users',
],
],
...Step 3
app/User.php
<?php
namespace App;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use Laravel\Passport\HasApiTokens;
class User extends Authenticatable {
use Notifiable, HasApiTokens;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'email', 'password',
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}Step 4
app/Repositories/User/UserRepositoryInterface.php
<?php
namespace App\Repositories\User;
use Illuminate\Http\Request;
interface UserRepositoryInterface {
public function register(Request $request);
public function login(Request $request);
public function refreshToken(Request $request);
public function details();
public function logout(Request $request);
public function response($data, int $statusCode);
public function getTokenAndRefreshToken(string $email, string $password);
public function sendRequest(string $route, array $formParams);
public function getOClient();
}Step 5
Create app/Repositories/User /UserRepository.php file
<?php
namespace App\Repositories\User;
use App\User;
use GuzzleHttp\Client;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Laravel\Passport\Client as OClient;
use GuzzleHttp\Exception\ClientException;

const SUCCUSUS_STATUS_CODE = 200;
const UNAUTHORISED_STATUS_CODE = 401;
const BASE_URL = "http://mylemp-nginx";
public function __construct(Client $client) {
$this->http = $client;
}
public function register(Request $request) {
$email = $request->email;
$password = $request->password;

}
public function login(Request $request) {

}
return $this->response($data, $statusCode);
}
public function refreshToken(Request $request) {
if (is_null($request->header('Refreshtoken'))) {
return $this->response(['error'=>'Unauthorised'], self::UNAUTHORISED_STATUS_CODE);
}
$refresh_token = $request->header('Refreshtoken');
$Oclient = $this->getOClient();
$formParams = [ 'grant_type' => 'refresh_token',
'refresh_token' => $refresh_token,
'client_id' => $Oclient->id,
'client_secret' => $Oclient->secret,
'scope' => '*'];
return $this->sendRequest("/oauth/token", $formParams);
}
public function details() {
$user = Auth::user();
return $this->response($user, self::SUCCUSUS_STATUS_CODE);
}
public function logout(Request $request) {
$request->user()->token()->revoke();
return $this->response(['message' => 'Successfully logged out'], self::SUCCUSUS_STATUS_CODE);
}
public function response($data, int $statusCode) {
$response = ["data"=>$data, "statusCode"=>$statusCode];
return $response;
}
public function getTokenAndRefreshToken(string $email, string $password) {

}
public function sendRequest(string $route, array $formParams) {
try {
$url = self::BASE_URL.$route;
$response = $this->http->request('POST', $url, ['form_params' => $formParams]);
$statusCode = self::SUCCUSUS_STATUS_CODE;
$data = json_decode((string) $response->getBody(), true);
} catch (ClientException $e) {
echo $e->getMessage();
$statusCode = $e->getCode();
$data = ['error'=>'OAuth client error'];
}
return ["data" => $data, "statusCode"=>$statusCode];
}
public function getOClient() {
return OClient::where('password_client', 1)->first();
}

app/Http/Requests/UserLoginRequest.php
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;
class UserLoginRequest extends FormRequest {
const UNPROCESSABLE_ENTITY = 422;
public function rules() {
return [
'email' => 'required|email',
'password' => 'required',

}
protected function failedValidation(Validator $validator) {
throw new HttpResponseException(response()->json($validator->errors(), self::UNPROCESSABLE_ENTITY));
}
}Step Seven
app/Http/Requests/UserRegisterRequest.php
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
use Illuminate\Contracts\Validation\Validator;
use Illuminate\Http\Exceptions\HttpResponseException;

'c_password' => 'required|same:password',
];
}
protected function failedValidation(Validator $validator) {
throw new HttpResponseException(response()->json($validator->errors(), self::UNPROCESSABLE_ENTITY));
}
}Step 8
app/Providers/AppServiceProvider.php
<?php
namespace App\Providers;
use App\Repositories\User\UserRepository;
use App\Repositories\User\UserRepositoryInterface;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider {
/**
* Register any application services.
*
* @return void

public function register() {
$this->app->bind(UserRepositoryInterface::class, UserRepository::class);
}
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot() {
//
}
} Step 9
app/Providers/AuthServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Laravel\Passport\Passport;
class AuthServiceProvider extends ServiceProvider {
/**
* The policy mappings for the application.
*
* @var array
*/
protected $policies = [
// 'App\Model' => 'App\Policies\ModelPolicy',
];
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot() {
$this->registerPolicies();
Passport::routes();
}
}Step 10
app/Http /Controllers/UserController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests\UserLoginRequest;
use App\Http\Requests\UserRegisterRequest;

const SUCCUSUS_STATUS_CODE = 200;
const UNAUTHORISED_STATUS_CODE = 401;
public function __construct(UserRepositoryInterface $userRepository) {
